Expand description

Fourier transform for 2D data such as images.

Functions

  • fft_2d
    Compute the 2D Fourier transform of an image buffer.
  • fftshift
    Shift the 4 quadrants of a Fourier transform to have all the low frequencies at the center of the image.
  • ifft_2d
    Compute the inverse 2D Fourier transform to get back an image buffer.
  • ifftshift
    Inverse operation of the quadrants shift performed by fftshift.
